.addClass('red') vs .attr('class', 'red')??

I just wonder, why I cannot set attribute class="red", with .attr function instead of adding class called 'red'.

You can use attr to set the class.

But if you do, you will remove any other classes the element had already. So normally you would use addClass instead since it preserves other classes of the element.

This doesn't seem related to the challenge you linked to.
